Both mushrooms contain bioactive compounds like beta-glucans that support the immune system. They do not interfere with each other's absorption or breakdown in the body. Instead, they may have a complementary effect on general health.

Disturbi emorragici o chirurgia

Both lion's mane and shiitake may slow blood clotting. This can increase the risk of bruising and bleeding, and may cause excessive bleeding during or after surgical procedures. Stop use at least 2 weeks before scheduled surgery.
